Rhinosporidiosis of Parotid Duct Presenting as Consecutive Bilateral Facial Swelling: A Rare Case Report and Literature Review.

Rhinosporidiosis is a chronic granulomatous infection caused by Rhinosporidium seeberi. Sporadic cases of rhinosporidiosis has been reported from many countries but is endemic in Southern India (Madurai, Ramnad, Rajapalayam and Sivaganga), Nepal, Bangladesh and Sri Lanka. This disease commonly affects the mucous membrane of the nose or naso-pharynx and presents as a leafy, polypoidal mass. The reported extranasal sites include the oro-pharynx, eye, ear, larynx, trachea, bronchi, skin and genital mucosa. It may also become disseminated to present as a generalized form. In our case a 40-year-old female from rural West Bengal (Eastern India) presented with right sided facial swelling. Our provisional diagnosis was parotid duct cyst on the basis of careful history, scrupulous clinical examination and relevant investigations comprising CECT scan of face. Although Rhinosporidiosis was not taken into consideration in the clinical differential diagnosis, it was eventually diagnosed postoperatively by histopathological examination of surgical specimen. Two months later in follow-up, the same patient presented to us with left sided facial swelling. We managed the left facial swelling successfully with minimally invasive surgery and 100mg twice daily dapsone for 6 months. We present this case firstly because Rhinosporidiosis of parotid duct (stensen's duct) is a rare entity and secondly non-neoplastic cysts of the salivary glands are also uncommon and represent only 2-5% of all salivary gland lesions. Furthermore our case emphasizes that the clinicians should aware of this rare clinical entity specially in endemic areas, because minimally invasive techniques and medications might solve the problem while helping patients to avoid surgical excision.

Acute Urinary Retention due to Primary Pelvic Hydatid Cyst: A Rare Case Report and Literature Review.

Causes of urinary retention in old men include benign prostatic hyperplasia, prostatitis, prostate cancer, Scarring of the urethra or bladder neck as a result of injury or surgery, use of certain medicines particularly NSAIDs and opioid analgesics, constipation and neurogenic bladder. When the above common causes are not quite obvious by clinical examination and relevant investigations, then it is necessary to think of other rare diseases. It is with the above in our mind that a case of bladder outflow obstruction due to a large primary retrovesical hydatid cyst is herein reported in a 58-year-old man. Ultrasonography (USG) and Contrast Enhanced Computed Tomography (CECT) scan of the abdomen and pelvis of the patient revealed a large, multilocular, nonenhancing, cystic lesion in the rectovesical pouch having typical cartwheel appearance without any other intraabdominal organ involvement. These typical radiological characteristics led us to suspect the presence of a hydatid cyst. He underwent exploratory laparotomy where cystopericycstectomy was done. Pre-operative and post-operative albendazole prophylaxis was also given. In conclusion, hydatid cyst should always be considered in the differential diagnosis of pelvic cystic masses, specially in endemic regions.

Hydrocele of the Canal of Nuck (Female Hydrocele): A Rare Differential for Inguino-Labial Swelling.

The inguinal canal is traversed by the spermatic cord in men and the round ligament of uterus in women. The round ligament is attached to the uterine cornu near the origin of fallopian tube at one end and to the ipsilateral labia majora at the other. The round ligament accompanies a pouch of parietal peritoneum in the inguinal canal, which is known as 'canal of nuck'. It is analogous to the processus vaginalis in males. Incomplete obliteration of the peritoneal pouch causes indirect inguinal hernia or hydrocele of the canal of nuck; a very rare condition in women. As these types of cases are rarely seen in surgical practice we present a case of such little-known developmental disorder in a three-year-old girl. She presented with irreducible, tender right inguino-labial swelling with tachycardia simulating incarcerated inguinal hernia, which necessitates emergency surgical exploration. On exploration it was found to be an encysted hydrocele of canal of nuck; so although rare, this entity should be considered in differential diagnosis in a female child presented with inguino-labial swelling.

An Unusual Transorbital Penetrating Injury by House-key (lock): A Case Report with a Small Review of Literature.

Penetrating injuries of the brain are quite uncommon, comprising approximately 0.4% of all head injuries. In our case, a four-year-old boy who fell forward on a house-key (lock) accidentally while playing with some other children sustained a left sided penetrating transorbital brain injury. After hospital admission, the patient had a Glasgow Coma Scale (GCS) score of 15/15, no visual loss but restriction of upward gaze (left eye) and profuse bleeding from the wound site. Firstly, the metallic key was removed in emergency operation theatre and haemostasis secured. Next day we did a combined surgical approach with neurosurgeons, Eye-surgeons and general surgeons after having CT scan report. We report this case because penetrating head injury is rare and transorbital penetrating head injury is even rarer and a predicament in emergency surgical practice with controversial management.
